gradual development of this system is possible by early next week

while it moves west-northwestward.

DORA FORECAST TO BECOME A REMNANT LOW LATER TODAY

Tropical Storm Dora Discussion Number 14

NWS National Hurricane Center Miami FL EP042017

300 AM MDT Wed Jun 28 2017

Microwave images indicate that Dora stopped producing deep

convection soon after 0000 UTC, and all cloud tops warmed above -50C

by 0245 UTC. The circulation now consists of a swirl of low- to

mid-level clouds, and the initial intensity is lowered to 35 kt

based on a blend of the latest subjective and objective Dvorak

estimates. Deep convection is unlikely to return due to cold sea

surface temperatures, and Dora is forecast to degenerate to a

remnant low later this morning or this afternoon.

Dora has slowed down with an initial motion estimate of 285/9 kt.

A low- to mid-level ridge to the north of the cyclone should

maintain Dora on a similar west-northwestward trajectory for the

next day or two. Based on the latest surface fields from the GFS

and ECMWF models, the remnant low is forecast to dissipate by 48

hours.
